Hypothesis
Can a multifunctional cellulose-based coating effectively preserve the freshness of fruits without refrigeration?
Conclusion
The cellulose-based coating significantly extends the shelf life of fruits by inhibiting spoilage and dehydration.
Supporting Evidence
- The coating inhibited E. coli growth by 94.69% and S. aureus by 100%.
- The water vapor transmission rate of the coating was less than 30 g·mm/(m2·day).
- The coating maintained the appearance of fruits while preventing spoilage for over a week.
- The coating can be completely washed off before consumption.
Takeaway
This study created a special coating that keeps fruits fresh for longer without needing to be kept cold. It's safe to eat and can be washed off before eating the fruit.
Methodology
The coating was made from cellulose microgel, montmorillonite, cationic cellulose derivative, and L-ascorbic acid, and applied to fruits through spraying or dipping.
